SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 552,559, dated January*7, 1896.

Application filed October 15, 1894. Serial No. 525,899. (No model.)

ing the string of beads laterally from side to side in advance of theneedle.

The particular machine which I have chosen to illustrate myinvention isof the type commonly known as the Cole universal-feed machine, althoughthe mechanism to which my present invention particularly refers may beadapted with slight modifications to machines of other types.

In the accompanying drawings, Figure 1 is a view of the machine in sideelevation. Fig, 2 is an enlarged view in end elevation, partly insection, at the needle end of the machine. Fig. 3 is an end view,partlyin section, from the opposite end of the machine. Fig. 4 is a view indetail in side elevation. of the beadoperating finger and the means foroperating it, and Fig. 5 is a horizontal section through line x 00 ofFig. 1.

The bed of the machine is denoted by A,

' the overhanging supporting-arm by B, the

vibrating arm for operating the needle-bar by Z), the needle-bar by Z),and the operatingshaft by W. These parts, as well as the rotarypresserfoot and supply-spool carrier D, with their actuating-gear d inmesh with the pinion d on the spindle d controlled by intermediatebevel-gear from a crank d for rotating the drive gear-wheel 61 are quitesimilar in their structure and arrangement to that of the Coleuniversal-feed machine hereinbefore referred to, with the exception thatthe crank d for operating the rotary presser-foot and supply-carryingbarrel is in the present instance located underneath the bed A, insteadof above it, as is common in the type of machine referred to. Thepresserfoot E, its lifting-cam e, and the supply-spool support 6 arealso constructed and arranged in a manner quite similar to that commonto the Cole universal-feed machine referred to.

My present invention is particularly directed to the introduction of alongitudinallyreciprocating drivebar under the control of thedrive-shaft of the machine for transmit ting to a bead-carrying arm areciprocating movement transversely across the path in which the stringof beads is fed, no matter how the direction of the path of the beadsmay vary. To this end I provide the hollow guide-tube F, through whichthe thread is fed down to the presser-foot and which is made to rotate,together with the presserfoot and supply-spool carrier, with avertically-reciprocating sleeve f, having an annular groove f, adaptedto receive the :forked end g of a connecting-bar G, which is secured tothe lower end of a longitudinally-reciprocating drive-bar O, in thepresent instance by a screw 9. The sleeve f is provided with avertically-elongated slot f in its wall, in which a guide-pin fprojecting inwardly from the sleeve f, is received for the purpose ofpermitting the sleeve f to reciprocate vertically on the tube F whilebeing carried in a horizontally-rotary movement around with the tube.

To a depending lug f, 011 the tube F and on the side of the needleopposite that from which the presser-foot E is suspended, a guide-arm Iis pivoted, as at c'. From its pivotal connection the arm I depends,slanting toward the needle b its free end extendin g downwardly into aposition slightly above the normal position of the presser-foot when itis in operation. The lower end of the arm I is provided with an eye i,through which a string of beads is to be passed before coming intoengagement with the presser-foot beneath theneedle. The upper end I ofthe arm I extends away from the pivoti at an angle to the arm I, formingthe arm in the end of an angle-lever. The end I, which is made shorterthan the arm I, in order to give the latter a more extended throw, has apinand-slot connection with a bar K, fixed to and depending from thesleeve f. In the present instance the bar K is provided with a pin 70,which works in a slot t in the end of the portion I of the arm I. Thereciprocating drive-bar O is connected to one end of a vibrating lever0, supported on the over- ICO hanging arm B of the machine, the oppositeend of said lever 0 being connected by a link 0 With one arm of anangle-lever C the opposite arm of said angle-lever being engaged With asWitch-cam c on a short shaft 0 carrying a gear 0 in mesh with adrive-gear c on the drive-shaft b of the machine.

In operation the movements of the reciprocating bar 0 are so timed withrespect to the movement of the needle that the guidearm I Will be rockedback and forth across the path in which the string of beads is being fedbetween each two consecutive beads on the chain, so as to cause theneedle 11 to descend upon opposite sides of the string intermediate oftwo successive beads to fasten the beads to the material which they areto ornament.

It Will be observed that Whatever be the position of the presser-foot,Which in the type of machine referred to is caused to keep the samerelative position to the path of feed, no matter how the direction offeed be varied, the arm I Will be caused to keep the same relation tothe presser-footi. 6., it will at all times be in such position that itslaterallyvibrating movement will be transversely across the path offeed.

Vhat I claim is The combination with a sewing machine having a universalfeed, a rotary carrier for the presser foot, a reciprocating needle andmeans for operating them, of a vertically reciprocating sleeve fixed torotate with the presser foot carrier, a depending guide arm pivotallysecured to the rotary presser foot carrier and provided With a laterallyextending branch arm connected with the aforesaid reciprocating sleeveto vibrate the lower end of the guide arm as the sleeve is reciprocated,and a vertically reciprocating drive bar having a swiveled engagementwith the reciprocating sleeve for reciprocating it While permitting itto rotate freely, and mechanism connecting the said reciprocating drivebar with the main shaft for operating it, substantially as set forth.
